Since we are using the react-i18n babel loader plugin, useI18n can only
be used once per file. Also we have to remember to add the istanbul
ignore next comment each time we use it. By moving this to a common
file, it can be easily copied and pasted when a new submodule is
created and we don't have to remember the rules when calling it.
This refactors the new file wizard to be more independent. Most of the
control is now done through the saga instead of splitting it between
react and the sagas.
Also fix a few issues while we are touching this:
- pressing enter now accepts the dialog
- newly created file is now activated in the editor
This separates the explorer files state from the fileStorage FileMetadata.
The latter contains extra info that the explorer doesn't need. This
will prevent rerendering each time the file contents change.
